Young Professional magazine was developed for a target audience of recent college graduates who are in their first 10 years in a business career. In its two years of publication the magazine has been fairly successful. Now the publisher is interested in expanding the magazines advertising base. Potential advertisers continually ask about the demographics and interests of subscribers to Young Professional. To collect this information, the magazine commissioned a survey to develop a profile of its subscribers. The survey results will be used to help the magazine choose articles of interest and provide advertisers with a profile of subscribers.

What is the approximate total value of financial investments?
How many stock/bond/ mutual fund transactions have you made in the last year?
Do you have broadband internet access?
What is your total household income?
Do you have any children?

1.) Develop 95% confidence intervals for the mean age and household income of subscribers
2.) Develop 95% confidence intervals for the proportion of subscribers who have broadband access at home and the proportion of subscribers who have children.
3.) Would Young Professional be a good advertising outlet for online brokers? Justify your conclusion with statistical data
